I second that, you should base64 encode values before encrypting and base64

decode them after decrypting to be safe.

Thanks for the idea.

Like this? Fails 500/500 times on my test.

------------------------------------
if ($EorD == "D") {
        $text_out = mdecrypt_generic($cypher,$text);
        $text = base64_decode($text);
} else {
        $text= base64_encode($text);
        $text_out = mcrypt_generic($cypher,$text);
} // endif ($EorD == "D")
------------------------------------

A quick test looks like this:
